fixes for the issues found in the other thread about 106.

this one handles undo differently to set whether a sketch is modified, so please test for situations where undo might be getting confused and forgetting that modifications have happened.

but in general, please test this release! as you can tell from the number of releases in the past few days, i'd really like to get these issues with saving files straightened out because it's, err, important.

106 should still be considered the stable release until some of you kind souls can pound on this one a bit and i'll change it to be the default download if everything goes well.


ABOUT REV 0107 - 2 March 2006

More tweaks to "Save" to try an iron out further bugs, though these
are more minor than the others.

+ cut/paste from the context menu (right-click) in the editor wasn't
 properly setting a sketch as modified.

+ set/unset the sketch's modified state as undo happens.
